I thought it would be cool to do something with a different shape/layout to usual, so I did this all vertical and stuff. Looking at it now, though, I probably should have drawn the tree taller to emphasise that more. Oh well!

Aww, thank you! The background wasn't aaall that non-lazy, those are like the most simplistic buildings ever. But yes, I did put more effort into it than just "Oh here I'll swirl a few colours around randomly, that'll do". So, I'm glad you like the way it turned out.
